When upgrading from Steelhead EX v1.0 to Steelhead EX v2.0, what happens to existing VM slots on the appliance? 

The VM slots are immediately available as enabled VMs. 

The VM slots need to be manually added by managing VSP using the VMware vSphere client. 

The VM slots need to be manually added by using the VNC console access provided within Steelhead EX v2.0. 

The VM slots need to be manually converted to the new format using the tools available in the Steelhead EX Web UI.
